A friend of mine has a slightly older version of BIAB...the jazz styles are the best I've heard anywhere, and far better than any arrangers out there. It's a pity that you can't play the styles "live" but have to input the chords ahead of time...still, the resulting midi file is very impressive and rivals completely multi-tracked SMF.

It does come with quite an extensive library of tunes (including a lot of standards) and there are more tunes available as well as optional style packs.

Pretty cool program, for sure. Apparently invented by a dentist way back in 1988.
